branch: master
commit 58bec884d5a911690c2f8e0ecca6a487bd2c9fe0
Author: Jonas Bernoulli <jonas@bernoul.li>
Commit: Jonas Bernoulli <jonas@bernoul.li>

    * lisp/epa.el (epa-show-key): New command.
    Users can move in `epa-key-list-mode' buffers using either
    `next-line'/`previous-line' or `widget-forward'/`widget-backward'.
    When using the first set of commands, then the cursor stays in the
    current column and that normally is the first column.  The key
    widgets do not begin until the third character of their respective
    All `epa' commands work regardless of whether the cursor is on the
    widget or before them.  The `epa-show-key' command did not exist until
    now because the `widget-button-press' already performs its task.  But
    because the widgets don't span complete lines we actually need this
    command too.
